I reload ....( 9mm, .40, .45acp, .38spl, .357mag and .44 mag) ...but all it means is, I shoot more for the same amount of money...but keeping costs down is part of the game ...so I do shoot a lot of 9mm.
I like a 9mm ....especially in the same platform that I choose to carry ..like in a 1911. I think the 9mm is great range practice / put 5 or 6 boxes thru a 9mm and maybe 1 box thru a similar gun in .45 acp ) and its a good range trip ( same feel coming out of the holster / some recoil / good practice ) - especially if you have identical 1911's - say 5" guns at the same weight, same sights, etc .
I don't practice with a .22 semi-auto too much for tactical training ...its cheap but it doesn't translate too well for me ( even with a conversion kit on the same gun say in .45acp ) ...its just way different on weight and recoil.
I do like a revolver in .22 ( like a S&W model 18 ) ....work on my draw out of holster, move to target, etc ....and then transition to a model 19 or 66 ( another K frame S&W ) in .357mag ( especially if they both are about the same weight, same length of barrel like 4" --- recoil is less --- but its still good practice coming in and out of the holster, etc ) ...
.22 semi-autos are fun to shoot ...Browning Buckmark, etc ...but they're just way different than any 1911 or DA/SA guns like a Sig ....in any caliber. So I kind of say --- take the .22's when its just a plinking day ...not a serious training day ...if that makes any sense.
