I've had my GSG for 3 years now. Likely about 10K rounds through it and runs flawlessly.
Sunday past was typical...a box of Federal Automatch (325rds)...one stove pipe, but my 12 year old gets those occasionally because he limp wrists it a bit.
I added this last year

The way the slide works their is a little slop in the stock slide alignment cone which allows a little play between slide and barrel, affecting accuacy.
With the addition of the ZR kit I cut the group sizes in half.
At 15m rested the gun easy groups an inch...at 25m 2-3".
My only complaint is the finish...it is not conventionally blued...some sort of paint which does wear more than bluing. Am considering cera-coating it this year.
All in all, a great little plinker. And whether .45ACP, 9mm or .22LR...a 1911 is a 1911
