Large Lineup of SASII Models - Muzzle Rise Comparison

I have 5 Bul pistols (and a 4.25” drop in non-ported barrel from DSC*). This essentially gives me the equivalent of 7 different Bul Armory SAS II guns.

I wanted to do as scientific a measurement as possible and compare the recoil (specifically muzzle rise) of these various pistols, so I set out to do that this morning at the range.

Setup - I have the MantisX10 training system (which I highly recommend by the way). For those who are unaware, it’s a small, highly sensitive Bluetooth movement tracker that attaches to your pic rail. It is capable of lots of awesome stuff, and one of the cool things you can do with this in live fire mode is the recoilmeter. This gives a bunch of interesting info for each shot, including the degrees of muzzle rise. For each pistol, I took 10 shots of Winchester white box 115gr fmj. I tried my best to make sure my grip and stance were as consistent as possible. Each gun was shot with a red dot mounted, but no lights or other accessories. The average muzzle rise results are below, from highest to lowest:

Ultralight - 23.8°
*TAC 4.25”- 20.1°
*EDC Compact - 19.9°
TAC 5”- 17.5°
EDC Pro Compact - 14.9°
TAC Pro 4.25” - 12.6°
TAC Comp - 11.8°

The results are mostly what I expected, with a few exceptions:

I’m surprised that the 4.25” TAC measured (very) slightly higher than the EDC compact. They are essentially tied, but I would have expected the TAC with its full length steel frame and full size grip to come in slightly better. I may have to re-measure those 2 on my next range trip.

The TAC Comp FEELS more than 0.8° “softer” than the 4.25” TAC Pro. Could this be in my head? Maybe - but it was corroborated by the range officers who shot a few of my guns also. Without measuring, I would have said that the comp was a major upgrade from the pro, based on feel. This says that at least when it comes to muzzle rise, they are closer than I would have thought. Obviously felt recoil isn’t only about muzzle rise, so I’m sure there are other things impacting this (overall weight and distribution, etc).

Anyway, just thought this was interesting and figured I’d share with the larger Bul Armory community.

Anyone in South Jersey interested in a range meetup?

I hit an indoor range about once a week. Anyone else in the area that might want to meet at the range occasionally?

Underwood 429DE reviews?

Thinking about adding a 429 barrel to my engraved Mk19 set (pictured above), mostly because I’m a completionist and I have the other 3 calibers 🤣🤣. I like to shoot all my guns,and can get Underwood 429 ammo for a decent price (~$1.50) compared to the MRI/GR stuff ($2.50+), but can’t seem to find any reports online of anyone using it and reviewing it. I know 429 is not very popular, but anyone on this sub use it and have anything to share? I am not interested in reloading at this point, and am only looking for reviews on factory Underwood 429 DE. Thanks!
