OP, if you want, I can post some of my videos from The Mall. It it the only UK site I regularly attend (as regularly as someone who lives in the US can, anyway), and for the last three visits, I have only used my pistols. I agree with what the guys above are saying - In several of the games I used up just about all my ammo - and I carry a lot. I usually have 3 50 round G17 mags, 2 22 round G17 mags, 4 16 round XDM mags, and 2 22 round XDM mags, plus 4 shells for my launcher. In two of the five games a day at The Mall I used up all my ammo, and one of the other 3 I was a captured VIP whom the one team forced to sit in a corner the whole time. One thing you need to remember with gas mags - they will always fail when you need them

. That's why you carry extras.
I have actually had a fairly extensive bit of training in the States with the real-steel versions of these guns, and while that certainly helps some, its just as the guys above said - play fast, play aggressive, and play sneaky.
My experience? I own soooo many pistols, and use them in both the US and UK. My collection includes: 2 VFC M&P 9s, 1 TM M&P 9, 2 WE G17s, 1 WE Springfield XD, 1 WE Springfield XDM, 1 WA Stryer-Voight Infinity 5` Prokiller 1911, 1 WA Stryer-Voight Infinity Government "Magna" 1911 (which I only just fixed in the last 10 minutes), 1 Umarex Colt Peacemaker SAA, and 1 WE SIG P226. I love using pistols, and I've even taken on teams of Polestar players over here in the US with my pistols only, even in open game sites. You just have to play a little smarter and a little faster and you will be fine.
