Part of the reason Finland was able to remain independent during this time was the fact they had a strong indigenous armaments industry. Finnish Mosin Nagant rifles are generally far superior to their Russian counterparts. Finland was also able to repair, recondition, and remanufacture Soviet tanks captured in action and these were in turn used against their former owners. One of the more interesting firearms used by Finland during World War II was their indigenous sub-machinegun, the KP/-31. First fielded in 1931, the weapon was designed by Aimo Lahti and chambered for the 9mm cartridge. The KP/-31 was in many ways similar to the various early sub-machine guns of the era like the PPSh, Lanchester, and Beretta. Several modifications were made to the firearm during its service life including the addition of a muzzle brake. I'm certain this sort of weapon also scares the heck out of Carolyn McCarthy as it has a shoulder thing that goes up, errr, a barrel shroud.

Kits for the KP/-31 have been available for some time, but there have been no BATFE approved semi-automatics on the market until this year. I recently picked up a semi-auto KP/-31 from Ryan Judy Sporting Goods (pictured above). Astute observers will notice that the barrel is slightly lengthened through the permanent attachment of the muzzle brake. Esthetically I think they’ve done as good a job as possible capturing the original as the additional length isn’t as obtrusive as NFA compliant PPSh semi-autos. I have a couple of the 36-round magazines and two of the 71-round drums for it. All of these are marked with the appropriate Finnish “SA” markings. I haven’t gotten to test fire the weapon yet, but the fit and finish are pretty good. One thing I can say about the weapon – it’s HEAVY! There is also no provision for a forward grip, so you’ll need to have one hand on the magazine / drum or use the sling to steady the weapon. I’m looking forward to getting this little beauty out – it should be a fun plinker, and as it runs on 9mm ammunition, it shouldn’t be too expensive to feed either.
Until next time!!!
