I really thought about getting one for a truck gun in 9mm to go with my G19 + 33rndrs. I guess it depends which caliber you prefer.
I like 9mm because:
2. 9mm comes in hollow points
3.if 16 rnds of 9mm doesn't stop it blah blah blah.
4. little bang sticks like these it's manditory to do at least one full mag dump everytime it's taken to the range.
Well if they even have them in stock. The local shops have a heck of a time finding them. Call them first..
I have the 9mm, nice weapon goes good with my G19. Can hit a 12 inch by 18 inch plate at 100 yards 8 times out of 10 the first time I shot it. With stock open sites. Worth the bucks if you ask me.
