I have a 21sf and love the gun. I shoot it weekly in USPSA and am up to 10k rounds on the gun. I also CCW the same gun and have settled on the carry clip method while using the Vanguard trigger guard from Raven for added safety. I dont so much have an issue with concealing the gun but my motto has always been to carry what I practice with. I have got to the point after shooting competition that I can pretty much shoot anything well. For that reason I dream of a compact version of the gun and twice now nearly bought the 30sf but got cold feet and changed my mind. My concerns are that I am gaining an edge for concealment with the 30sf but am not sure that really is an issue so what then am I loosing in terms or recoil management and accuracy? The other idea in my head is that the mags are the same size. My off side carries 2 mags which print a hell of a lot more then the 21sf so what then would it matter having a 30sf when its going to use the same mag pouch. I am aware of the smaller calibers and glocks but I love and wont change from 45acp nor like the idea of a g36 given its history. I hope that the 30sf has its bugs worked out and the one I checked had the newest -1- cruciform so I should be in the clear. The one issue I had at the store was getting the slide off and the guy told me I was doing it wrong, lol. He tried 3 more times then passed it off to another who forced it off. This gun has been handled since Sept in the show case and I watched them assemble the top end with the recoil spring NOT in its assembly notch so who knows what was done to it but its not the one I am taking home. I do have a USP HK 45 compact and like the gun but not as much as my glock. What I do like about it is that all my fingers fit on the frame vs the 30sf where the pinky rests on the mag and needs to be moved when changing mags. The pinky issue on the 30sf is also a big concern of mine and I really dont like the idea of having all my fingers not fit on the frame. Please help me sort out the mess in my head. At this point I am leaning toward another 21sf dedicated to CCW and the one I currently have dedicated toward competition.
