about anything, much less about some post on the net. I"m not playing any bs games about I can 'only have' one gun. There's no way that you can cover all the needed bases with less than 2 guns and if you want to be really good and versatile, you'll need 3. You need the silenced AR and .22 unit, and a pocket 9mm pistol and if you're young and still need to shoot a lot, you'll also need a very similar 9mm belt gun, cause the pocket 9mm's can't stand up to the 1/4 milllion rds you'll need to shoot in order to get and stay proficient. I would not subject the pocket sig to nearly that much shooting, not even thru the .22 conversion unit, cause its slide stroke is so short, and it's got an aluminum frame. Even with the Commander and using the .22 unit for 3k of your 5k of rds per year, you'll probably have to replace the frame several times, Guns just dont hold up to hundreds of thousands of rds of full powered centerfire ammo, especially not alloy framed guns. i'd do my usual mod of the frame and the mainspring housing of the commander, of course, to relieve the stress normally put on the frame, right below the MSH retainer pin.
