We've had both the AR15s and the conversion units for a while now. Cheaper way to just have fun with them, especially indoors where we can't shoot 5.56mm.
For a combo Xmas/anniversary present, I just bought myself a S&W M19 2-1/2" snubby. If you can believe it, my wife forgot our anniversary! I'm soooo glad it wasn't the reverse. I bought her a 'Muddy Girl' hoody to go along with all her other 'Muddy Girl' stuff, including her black Corolla seats covers and AR15.
She had already bought herself a $4000 sewing machine (cleared out at a mere $2400), so that took care of her anniversary and Xmas presents in one fell swoop.
The snubby M19 is a companion piece for the S&W M66 2-1/2" I already have. The ideal CCW, IMHO. If I could legally pack a gun, this would be my first choice.
On this side of the DMZ, if you didn't own a handgun with a 4" or shorter barrel before 1995, you never will. They are now "prohibited", not "restricted" like handguns with 4.2" barrels or longer. Makes the world a safer place, right?
Those of us who did are "grandfathered" and can only buy and sell amongst ourselves. About 250,000 of us left.
