Not as good as SBA3 Predecessor

by -

Although it is more substantial in size (longer and wider), I feel the quality is not as good as it predecessor.

I love this pistol brace. I only wish that it was available when I purchased my SBA3. This is a solid made brace and give me larger cheek pad perch area. The SBA3 wrist supports would always collapse and feel a little cheap, you don't get that with the SBA4. I'm going to replace my SBA3 with an SBA4.

Best brace yet.

Love the fact it is adjustable, Easy install.

SBA4 or SBA3


I've got both the SBA3 and the SBA4. <br><br>Through extensive testing, using both in two different training courses, here's my opinion.<br><br>The SBA3 is lighter and has a smaller profile. It serves its purpose, but tends to give way and feel a little "mushy" under a lot of stress. It does however do a decent job of stabilizing. It adjusts easily and is great if you are looking for a minimalist brace for your pistol.<br><br>The SBA4 is heavier and is a more robust brace with several features that I prefer. Everything about it feels more solid and there is no give when stabilizing. The adjustments on the SBA4 are pretty stiff and it makes it more difficult than the SBA3 to move, but there is no rattle or slop. It definitely gives a different feel to your pistol, and depending on your application would be a welcome addition as it gives you more support.<br><br>Overall I am pleased with both braces and their performances.

More Sturdy Than The SBA3

First of all, I can't give primary arms enough props on the way they get their products sent out. Ordered late Friday evening and still received the brace on Tuesday. This is the same on every order I've placed through them. Now for the brace, I have the 3A and the 4A. They both do the job for a "brace" but the 4 is alot more stable and study then the 3. The 3 has a lower profile but the lower rubber on the brace doesn't hold up as well under realistic use. Just go with the 4, while you can, you won't be disappointed. Thanks primary arms.
