Hello I'm new to the site and had some questions about these rounds.I'm going to be buying another pistol before too long and I am trying to decide what caliber to get. I had been wanting a 45 for awhile(specifically a commander sized 1911) but lately have been thinking of maybe a Sig Pro in 40S&W or 357SIG because I can get the conversion barrel and switch between the two.Unfortunatley I probably won't get to shoot any of them before I buy.From what I understand and have read on here the 40's recoil is more snappy than the 45 and the 357 is similar to the 40 but yet different.I have a Ruger P94 9mm and though I haven't got to put alot of rounds through it I do like it quite abit.Also what is the recoil of these rounds like in comparision to the 9mm.I may use it for CCW as well as I plan on taking the training course at the end of this month to be able to get my permit.Basically I like guns and want another one but am only going to be able to afford to get one right now.I just wanted to to get some opinions on these guns and calibers and if you had to pick one what your reccomendation might be.Thanks.
