I have carried a Springfield Armory XDs 45 and it works for me. I had a Kimber Ultra Crimson Carry II that I intended to carry and came close but it always acted up so I didn't carry it and sold it off. I have a Ruger P345 that I have considered carrying but have not due to size. It is a great gun so I may! Now, I have a Ruger SR1911 full size that I may carry sometime in the future after I shoot enough to trust it and get a good holster. The only thing about the P345 and the SR1911 for carry is the size and concealability!
