v1911 are you new? The 9mm 1911's come with 9 round mags. If you buy 9 round mags, guess what, you load to 9. If you load to division capacity of 9+1 that would equal 10. For some stages, that would be an advantage.
All 9mm 1911 are subject to shitty mags and most of the malafunctions are caused by them. I have used several different brands and I have made all of them fail. I will try and pick up some Tripp mags down the road to see if they adressed the nose diving issue.
1911's are also picky with ammo. If I stuck with FMJ RN, I had little to no issues. Flatpoints would give me issues from time to time.
Now Mecgar double stacks, on the other hand, are bulletproof. I have probably had 20k rounds go through my CZ and the only issues I have had was when I tried utilizing the Grams engineering springs and followers to up my capacity from 20 to 23. 7 of the 9 mags I modded failed and nosedived. Other than that, My CZ's have run whether or not I cleaned them or if the mags were full of sand.
