I am looking to buy or trade for a Kel-tec sub-9 rifle in 9mm. I am looking for the rifle that takes sig p-226, glock or beretta magazines. I am also looking for sub 9's in 40 cal and 357 sig. In addition, I am looking for any parts or accessories for these rifles. I have a sub-9 that takes smith and wesson magazines I could trade but I also have cash. Thank you.
