To add, the approach to extraction is different with the Glock having a small extractor being pushed by a drive rod, plunger and spring assembly. The Stoeger’s striker tip is conventionally round like most firing pins. As most Glock owners know, the striker’s tip is a vertical rectangle. The slide assembly disassembles in most of the same way as a Glock and features similar ingredients. However, even that pin is slightly different in length.

Although most of the small parts look identical to the opposing brand’s, nothing but the locking-block pin was interchangeable. The frame’s action parts are so visually close that I disassembled every part on both pistols and attempted to interchange them. Though these pistols look different, functionally, the STR-9 is closest to a Glock. There are 38 parts to a G17 and 41 that make up the STR-9. The trigger-pull weight is similar and, like a Glock, before its slide can be removed from its frame, the STR-9’s trigger must to be pulled after pinching and pulling down both sides of the slide-lock crossbar. Although the slide and barrel are slightly shorter than the Glock 17, the profile of the pistol is close. Internally, I found that the STR-9 is most similar to full-size Glock Gen 3 models. That said, Stoeger is looking at offering fiber-optic and other sight options for the pistol soon. The steel sights are dovetailed into dimensions that mirror the SIG Sauer P320, but here’s a disclaimer: If you were to replace the STR-9’s white-dot sights with those made for a P320, you’ll find that the point of aim versus impact are off, which would require gunsmithing to zero the STR-9 effectively. The frontstrap’s three finger grooves and texture are similar to those found on the HK VP9.

Those three finger grooves coincidentally measure 1.5mm deep, just like the VP9’s. Looking at the frontstrap, the finger-grooves simulate those found on Heckler & Koch’s VP9.

Inspiration from the M&P9 continues as you compare the interchangeable backstraps, which feature a similar saddle design with a checkered backstrap and pebble-textured palm swells. You might see the scallops and proportions of the Smith & Wesson M&P9. For example, look at the STR-9’s slide and dust cover ahead of the breech. On first inspection, it looks like an amalgamation of several different pistols from brands with enviable reputations. However, the STR-9 has very aggressive backstrap checkering. The STR-9 utilizes an interchangable saddle-type backstrap similar to the ones on an M&P9.
