Product Information

Vihtavuori’s 3N37 handgun powder was originally developed for .22 rimfire cartridges, but has since proven to be very versatile and desirable within all competitive handgun shooting disciplines.

The 3N37 is tubular, porous powder type with grain dimensions of 0,6 mm length and 0,6 mm diameter. The symmetrical grain size makes metering a breeze in powder measures. The burning rate of the 3N37 is close to N350 and on the medium scale of our handgun powders.

This is an excellent powder for 9 mm major loads for IPSC open competitions and it’s very popular in USPSA and IPSC practical pistol shooting disciplines. In addition to practical shooting, 3N37 is also widely used as a submachine gun powder. As all of our powders, 3N37 offers consistent, extreme precision, with clean burning – and that is why it is used by the best shooters in the world.

Interesting fact: 3N37 was used back in the 1940’s by Sako for loading 9mm submachine gun cartridges.

An Excellent Handgun Powder

By Chris B. on Sep 13, 2023
In the beginning I picked up a couple of pounds of 3N37 when 340 was out of stock and have not been disappointed. 3N37 ranks right up there with cleanliness, accuracy, and versatility. The burn rate is very close to CFE Pistol and HS 6. VV powders have always been a bit more expensive, but in many ways the price is easily justified. If you’re on the bubble on trying this, I felt the same way myself. I’m very happy I gave it a shot. Get 3N37 and N340, you’ll be happy with both!
