Respondents can select multiple calibers. It appears the percentage given for results isn't the percent of total responses, but the percentage of respondents who selected that caliber, possibly along with other caliber(s). Best guess.
I agree, a non folding option would be nice. I'll still get one anyway though.
Back to the original question, 40 will be nice and easy for them to make. Might have to get 2 of them.
5.7 would be cool using their M&P pistol design. Not sure how useful 5.7 is but it sure is cute and fun.
10mm would be a beast.
Why not 38 super? I would love to see a 38 super....or a 356 TSW.
I would like to see this in 10mm, although I got tired owaiting and started purchasing parts for an AR version. Also 5.7x28mm. Also tired of waiting and purchased a AR57 upper. The 30 Super Carry would be nice unless this is really going to die off soon. This might be the only way to keep it alive. To me, the 10mm should have been made before the 40SW. The 40SW could have been modified out of a 10mm or vice-versa since the 40SW is out now. These should all be easy since they are blowback guns. Also, mag wells could have been made with special, permanent adapters instead of changing the entire receiver design.
