I apologize if this has come up before, I tried searching but could not find a thread regarding it. Anyway, I've recently purchased a SUB-2000 Gen 2 in 9mm, yet Kel-Tec will swap out the 9mm hardware, barrel, etc. for a small fee to the larger round. I've looked up most any kind of video/article regarding the two, yet cannot come to a decision on whether to keep it 9mm, or to upsize to the .40cal. I have no other 9mm guns in my collection, yet a few .40cal (if that makes a difference). If anyone has any info, or an opinion, please feel free to post a reply. Thank you in advance!

After reading this thread, I got interested in the 9 to 40 swap. Sent my used 9mm Kel-Tek and got back a new 40 cal one in about 2 weeks from the day I sent it in. After installing all the Mcarbo hardware bits back in the rifle plus Kaw Valley linear compensator, I headed to the range.
WOW! Gun is quieter, smoother, and hits the steel gong with a "crispier" sound. The gun is better in every way! I brought 200 rounds of 40 to the range, thinking I would also practice with my Glock 23(not a fan but one must be proficient with every gun you own, otherwise, why own it in the first place). Well, that G23 never left the holster! I just couldn't get enough of how awesome the rifle has become!
With all this "hating on 40" bull going on, people are missing out on what I am now convinced is the best Sub2K rifle. The best and cheapest(only $40) upgrade you can do to your 9mm Sub2K is 40 cal conversion.

Me personally, I have never owned a firearm in .40 caliber and never will. The ammo for it is too hard to find where as 9mm ammo can be found almost any where. The fbi, fools big idiots tried the .40 and decided it was no better than the 9mm. Your mileage may vary but I will never own a firearm in .40 caliber.
