A guy I work with is who got me into shooting... and if it wasn't for him owning a small arsenal of various semi-autos from .22 to .45 I wouldn't have gone out and bought my own firearm.
I shot a Kimber 1911, Desert Eagle .45, Baby Eagle 9mm(also with a .22 conversion kit), an XDM 9mm, a CZ Rami something or other .40, and some oddball little cheap pistol with stupid magazines that you have to rip out to change/reload... it was something weird like .32 or so.
I ended up buying a blued Colt 1911 Commander .45... and LOVE it.
I've been to the range about 3-4 times since buying it, and the last few times I've let others shoot it, while showing interest and asking what they are shooting... and offering to see if we might exchange to shoot a magazine or two through.
I found a guy shooting a Springfield 1911 Target Loaded model in 9mm... I asked how he liked it, I love my 1911 .45 but am looking for a 9mm something-or-other next... he let me shoot his and I let him shoot mine.
That was the absolute softest shooting and most fantastic 9mm I've shot yet... and the other guy seemed to enjoy my Commander too.
Also, there was another guy who just bought a Sig P250 9mm who was just getting used to shooting in general, he got some safety and general shooting tips from the range officer, and after a while he was doing alright, but still shooting all over his targets. I asked how he liked his P250 because I was considering one potentially in 9mm... he said he liked it but couldn't shoot accurately with it at all, but it was his first time shooting etc etc. I asked if he would mind if I shot a magazine through it(I had my own 9mm ammo, I was renting an FNP9 to try out as well) to which he was fine with.
I couldn't hit crap with it... that DA pull was horrific
But I was at least keeping it in a 12" group... at 25ft... ha! I asked if other guy would want to shoot my Colt, he was kind of nervous because it was a "big" .45 caliber... I told him that due to the weight of the gun it is really not terrible... I find it better than super lightweight 9mm pistols... 45 isn't as snappy... it's more like a quick "shove" than a hard "snap" from 9mm or .40. He wanted me to shoot a few through it so he could gauge the recoil of it by me shooting it... so I shot a few and he seemed impressed in that it wasn't crazy looking.
So I let him shoot it and he managed to get a 4" or so group at 25ft on his target... better than he had done with his own gun... he seemed very impressed with the 1911 platform and he said something about he may consider buying one in the very near future
Now I need to find somebody with a Ruger SP101 and LCR, and someone with an M&P 9 or 40 to trade with
