I am an avid IPSC shooter with large hands, and have found my Limited gun built on an SV to fit my hands almost perfectly. However, when I shoot my Kimber carry gun, I feel like I do not have complete control of it. I have had the front strap serrated, and have the thickest grips I can find fitted to it with an SA mag funnel, but it still feels too small. Because of this, I am looking at having my gunsmith build me a carry gun on an STI frame. I have heard that in 45 reliability is spotty, but in 40 and 38 they run like champs. I can vouch for the reliability in 40, since my gun only has troubles when I feed it bar reloads. But, relibility at a match is nice, relibility in carry is an absoulute need. My question really revolves around a having a gun built in 40, 5" with fixed sites, no mag funnel, and a bull barrel. Can a gun be made to these rather general specs and be reliable enough to bet my life on it?
