Precision is a word you hear a lot in the gun world, and when you say precision out loud in Germany it carries history behind it. The German tradition of gunsmithing stretches back centuries, long before our country the United States even existed. And when you walk into a shop like STP you can feel that lineage in the air. In September I hopped a flight to Germany to visit Karl Prommersberger’s workshop in Kübach and to see, up close, how a modern German pistol is imagined, machined, and finished. What I found was an old-school respect for craft married to modern engineering discipline, and a shop culture that produces pistols built to be used, tested, and trusted.
Karl’s Journey & Launching STP
Karl Prommersberger opened his gunsmithing doors in 1988 and by 1990 he had a full workshop and adjoining production space. For decades he worked in large-caliber sport pistols, training and trading ideas with people like John Nowlin Sr. and Les Baer. He was instrumental in popularizing STI-pattern pistols in Europe and he even held the STI brand rights for the continent for a time.
In 2015 Karl ended that cooperation and in 2016 he launched STP (Sport Target Pistol) as his own, independent brand. Since then STP has focused on premium competition 1911 and 2011 platforms, and their catalog reads like the wish list of an elite IPSC competitor or a shooter who values one perfect tool for many tasks.

Karl’s story matters because it explains what STP is and why their pistols feel different. He is a gunsmith who came up through practical experience and competition, then layered modern machine work over old-school bench skills. That combination is at the heart of German gunsmithing in the modern era.
The German mindset
To understand German precision you have to understand the system that surrounds it. Germany’s trade and apprenticeship model produces craftsmen who are trained for years before they are allowed to call themselves masters. Everyone in Karl’s shop is a trained gunsmith who has been to trade school and logged bench time before they touch a customer pistol. That investment in people matters because a high-quality CNC program still needs experts who understand how to file, fit, and hand-finish parts to behave exactly as designed.

Legal context also shapes what the shop makes. German firearms ownership is tightly regulated and tied to demonstrated participation in shooting disciplines. In practice that means you can collect, but you must document trigger time and competitive use to retain ownership. Concealed civilian carry is narrow and uncommon, which places an emphasis on buy-once, keep-forever products. The market is populated by customers who will keep fewer pistols but expect each to be exceptional. That expectation raises the bar for makers like STP and it informs every decision from material selection to serviceability.
What STP Makes
Karl’s product line is essentially variations on the 1911 and 2011 platforms. Models such as IGEL, LOKI, LISA, and SPARTA demonstrate STP’s approach to class and purpose, ranging from classic precision pistols to wide-open race guns. Frames and slides are milled from single billets of stainless steel and smaller components are wire EDM’d or CNC turned to exacting tolerances. The idea is to reduce variability at the source so that the final hand fitting is minimal and repeatable. The shop’s aim is a tight aggregate stack where everything lines up so precisely that the smallest tweak yields meaningful performance improvements.

On the bench the team focuses on practical shootability. Triggers are tuned for clean breaks, slide rails are fit for smooth cycling, and the geometries are designed so that the pistols work well under the pressure of competition. Where other makers might leave a part-shaped gap between component tolerances, STP tightens the stack so performance becomes predictable and enduring.
Kübach: The Shop & the People
Kübach itself is a small German village, the kind of place with a brewery, local history, and a community that still values craft and continuity. Walking into Karl’s shop felt familiar in an American way, but different in a thousand small details. Machines hummed; files and stones rested beside digital readouts. The air smelled of oil and steel and the rhythm of work had a cadence that made you aware of time spent learning a trade. Everyone on the floor knew their role and could speak to why a particular fit or finish mattered.

What struck me most was the consistent thread of quality across the whole team. This is not a shop that depends on a single master for quality control. Instead the process is distributed across trained hands and precise machines. That design makes the product resilient and repeatable.
Perfect Classic & LOKI
STP is sending two pistols for testing, but I got nice and close to them in Kübach during my visit. A Perfect Classic in .45 ACP and a LOKI double-stack in 9mm. The Perfect Classic is a modern take on the 1911 platform. It looks familiar at a glance but the details reward inspection. Tight slide-to-frame fit, crisp control surfaces, and a trigger that breaks like it was tuned for a single number on a scorecard. Despite its precision leaning, the Perfect Classic is not an unwilling defensive pistol. It will take carry holsters and tolerate real use, which is the kind of duality German shooters value, but more importantly it’s what wins minds here in the states.

The LOKI is the sportier option, a double-stack 9mm designed with competition in mind but built to handle hard use. It is wider at the grip, flatter through the sights, and configured to accept high-capacity magazines without compromising reliability. Both pistols show STP’s approach of machining primary components from billet and then finishing with handshake-level fitting. Out of the box they felt like instruments rather than consumer products.
Technical Notes
Frames and slides milled from single stainless billets give parts maximum stiffness and repeatability. Wire EDM’d internals allow tolerances you often only see on bespoke competition guns. Those manufacturing choices are expensive but they reduce the amount of hand fitting required and increase the likelihood that each pistol will behave identically to its siblings. STP focuses on the aggregate stack such that optics cuts, barrel lockup, and feed geometry align to produce repeatable accuracy and consistent function.

Part of STP’s appeal is the serviceable architecture. Their pistols share dimensions with common 1911 and 2011 standards so aftermarket grips, holsters, and many service parts are easy to source. That compatibility is a practical advantage for buyers who prize both premium construction and real-world support.
Impossible Triangle
When I evaluate a pistol I look at three corners of an impossible triangle: aesthetics, accuracy, and hard-use durability. STP’s designs score highly on two of those corners out of the box, and they work hard to earn the third. The pistols are undeniably beautiful in a restrained, German way. They shoot with the kind of accuracy that lets you trust the pistol at competitive distances. And because the internal components are machined and heat-treated rather than relying on mass-produced sintered parts, the pistols handle hard use with far less worry.
STP ranges from roughly 1,899 to 8,000 euros depending on configuration and class. Those prices reflect everything from old-school target 1911s to feature-loaded open-class race guns. For the buyer who values longevity, the numbers make sense. You pay for repeatability, for parts that resist wear, and for the trained hands that finish every piece.

American Shooters
Even though STP builds to a German market, American shooters benefit from the same discipline. Many of us drown in options and in a market that prizes novelty. A buy-once product that prioritizes longevity and serviceability is a different offer. For action shooters, the STP pistols are tools that will get better over time and can be tuned to the shooter’s needs. For serious hobbyists, owning an STP pistol is an exercise in understanding how a platform can be engineered to solve problems before they appear.
Final Shots
Visiting Karl and his team in Kübach was a reminder that great guns start with great people. The apprenticeship model, the regulatory environment, and a cultural emphasis on craft all shape the way STP approaches pistol building. What the company produces is not flash for flash’s sake. It is a disciplined, repeatable product designed to be used hard, tuned for accuracy, and made to last.

In short, STP pistols feel like they were built by people who know how to make precision reliable. If you want a pistol that brings bench-level tolerances to practical shooting, STP is a shop worth studying and a brand worth trying on for size.
