I'm not saying it isn't a good gun. I'm just saying I think it wise to take a wait & see attitude. For whatever it's worth unlike many on the forum boards I like .40. I like it in a compact (G-19 or 23) sized pistol or a full sized. I own a Kel-Tec P-11 in 9mm that weighs 14 oz.'s unloaded. At one time Kel-Tec offered a .40 caliber version of this gun. I would not want to shoot a gun that size in .40. Maybe the R-51 would be better but like anything else I'll believe it when I see for myself.
