No, because not much is being innovated. The Sig P320 may be, but I like muh Glocks more. I find it hilarious, yet sad that I can buy different sized used Glocks for less or the same as those kits for the Sig P320. Actually, I can't find those kits anyway, but I have a pick of the litter among used .40 caliber Glocks.
And they're all guns, so I always have them ready for action, but a bunch of barrels and plastic frames for different occasions... nah.
Ruger coming out with their carbine all but killed any interest in me with the Mechtech uppers. Why spend money on something that requires a lower when the Ruger is a full gun that costs about the same?
That Bond Arms bullpup that was bought from Boberg? I don't trust it. The manufacturing and machining and engineering I have the utmost respect and appreciation for because I've been in that spot before where you're given prints for parts and are told, "make this."
But, the way it functions by pulling cartridges out of the magazine and not pushing them out and up a feed ramp to me screams novelty gun and not to be used for anything serious.
If you ask me, everything Bond makes is a novelty gun, but I digress.
The barrel being a half an inch longer does NOTHING to increase velocities to a significant extent to make it more powerful or effective. Most modern defense ammunition is built to expand and hit its intended velocities out of 3 inch barrels. Going from 3 to 4 inches typically equals an extra 30 fps, but that longer, bigger gun doesn't make it more effective. Maybe a bit easier to hit with because of sight radius, but the Bond Arms Bullpup doesn't add any sight radius either.
The Chiappa Rhino is an interesting design, but it's not an innovative one. What would make me buy one is if it were available in 10mm or .45 Colt. Those in a 2 inch snub with the lower recoil would make excellent carry revolvers. I don't have to worry about reliability or working in the heat of the moment because the revolver design is simple. What keeps me from buying them is they don't exist and if they did, they'd cost 1000 bucks.
Sorry, the Charter Bulldog On Duty is $375 and comes with the best customer service in the biz.
The most innovative gun I would buy would be something multi-caliber, like the M47 Medusa that could fire something like 30 different cartridges. At most all I'd want is .357 Mag, 9mm, .380, and .38 Super.
