Ditto what Desertmoon said, you can replace some of the crap parts that SA puts in and end up with a very reliable handgun. I bought a used SA Mil-spec a couple of months ago, I've replaced the barrel bushing with a tighter one, replaced the slide stop, firing pin stop,and extractor This pistol shot flawlessly before I changed parts, 500 rnds No malfunctions. Since the parts change, I've shot another 200rnds through it, No malfunctions of any kind, The diffrence here is, there will probably not be any problems because the parts I've changed are much higher quality than stock, I feel I can expect many years of flawless shooting, well worth the $80 or I spent on parts. There tons of aftermarket parts for a 1911, There are very few for an Hk.... A reliable 1911(and I have two) is a joy to shoot
