M11/nine to .380

[3154tm]

installed a .380 acp barrel in a dedicated upper for an SWD M11/nine. it runs like a train. it uses the same 9mm mags or a converted 9mm mag for .380 acp. it's nice to be able to shoot another caliber in this lower. although, i did this mainly because the 380 round is very quiet when suppressed.

Did the rate of fire slow down with the .380 conversion?

daezee, interesting observation. that was what got me started on this project in the first place. i wanted slow it down without having to buy another expensive after market upper while keeping the oem compact size. i would guess it's around 800 to 850 rpm now. as you know, much slower than the oem 9mm upper. it uses the stock bolt, extractor, recoil spring and buffer.
