Blowback9 — Sun, 08 Nov 2026 18:16:40 GMT

High speed video testing showing that firing pin bounce does occur in 9mm bolts and is a likely cause of Dead Trigger/Light Strike problems with rapid firing triggers in 9mm AR's.

[189] BoreBuddy 9mm No-Tune FRT Upper Range Tests: Hollow Points, Lowers, and Accuracy

Blowback9 — Fri, 06 Nov 2026 00:00:00 GMT

Testing the 9mm No-Tune FRT Upper Receiver from BoreBuddy to see how it cycles hollow points, if it works with a Spikes lower, and general accuracy.

It has a great set of features and is poised to become my go-to recommendation for a complete 9mm upper for both FRT and non-FRT use, which is something a lot of people have been asking for!

[188] Earmore Amplified Earbuds at the Range, feat. Mrs. Blowback9.

Trying out the Earmore amplified earbuds at the range with PCC and Pistol. Mrs. Blowback9 makes a cameo appearance.

TL;DR, they worked well and we both think they are worth checking out if you are in the market for amplified earbuds.

The Earmore amplified earbuds were provided with absolutely no obligations or stipulations from Earmore. Since we did like them, we decided to make a video to share the details and results to help viewers make an informed decision. We are planning on continuing to use them while shooting, so you should see them in future videos.

[181] Unicorn! Early Original Colt 635 SMG 9mm AR Bolt

Blowback9 — Fri, 16 Oct 2026 00:00:00 GMT

I received an early original Colt 635 9mm AR bolt on loan to measure and photograph. If I have my information correct, this is one of the very early 9mm Colt bolts made somewhere from 1982-1985 before 9mm AR's were available to civilians. It's a very neat piece of 9mm AR history. Big THANK YOU to the person who sent it to me on loan.

[180] 9mm AR drop-in FRT-ready bolt weight and XP firing pin spring. NO GRINDING!

MSRX-USA is making 2.7oz. pre-trimmed hardcast cylindrical bolt weights that fit many 9mm AR bolts. No more cutting or trimming the 9mm AR bolt weight for certain triggers! They also stock the 2x firing pin springs individually to prevent dead trigger/light strikes which is a common failure with 9mm AR's using certain triggers.

Weights are available as pre-drilled or solid if you want to drill it yourself.

Firing pin bounce may be the primary cause (other than bolt bounce) of the dreaded Dead Trigger/Light Strike problem with FRT's in 9mm AR's. Here I test 2 possible replacement stronger firing pin springs that may solve the firing pin bounce problem once and for all!
