Truer words were never spoken. The Sterling 302, however, falls into the 10% that won't always improve. The little gun evolved as a series of design flaws were noticed and "corrected" by the factory. One of them was the dimensions of the ejector port, which I've opened up on one of my 302s using the vertical mill, to allow the pistol to eject easier. Another problem was that the gun could discharge when dropped, which they addressed by installing a very heavy trigger spring and increasing the sear angle to the point of being ridiculous. NEVER CARRY THE 302 WITH ONE IN THE CHAMBER. Thanks to this heavy spring and sear combination, the blowback is oftentimes not powerful enough to completely cycle the action, and the sear does not "latch" with the firing pin. The sear needs careful stoning and the springs need changing, in my opinion.
If you're willing to address some of these issues, you'll wind up with a marvelous little pistol at a bargain-basement price. If you try hard enough, it seems that you can
make a silk purse out of a sow's ear.
