Description
Our Stribog A1/A2/A3 spring kit provides a crisp clean 4.5-5.0 lb trigger pull (down from 6.0-6.5 lbs factory trigger). Simply remove your factory hammer and disconnector springs and replace them with our application specific hammer and disconnector springs. Both springs in our kit must be used together. Our springs have been designed specifically for use with the factory hammer, hammer pivot/bushings, sear, disconnector, trigger return spring and trigger housing. We have found that retaining the OEM trigger return spring produces a quicker more positive reset than kits which include a reduced weight trigger return spring.
NOTE: Our spring kit DOES NOT fit Stribog 10mm or 45ACP variants.

It’s an improvement, but it’s still too heavy for a 9mm pdw. Would like to find something in the 3-4 lb range.

For less than $10 this spring kit significantly drops the trigger pull. The HBI kit has met my expectations & I can’t wait to take the Stribog out.
Takes about 10-15 minutes to install.

Absolutely a great upgrade make sure to watch a video before doing. Has a few spring loaded step that can easily cause major issues if not done properly. A lot of plastic parts in the Stribog so watch the videos first.
With that said this was very easy to install and made a great improvement.

Phenomenal upgrade! My factory trigger was consistently 6lbs, with this kit it’s now just a hair over 4lbs. Way better than anticipated. Also, much cleaner and more crisp. Definitely watch a couple videos, but really easy install. DO IT!!!

Huge improvement in trigger feel. I hated how heavy the stock trigger was for a 9mm. This reduces it to a perfect weight for me. Its not a precision rifle so no need for a super light pull, this one is just right. Would be nice if HBI made their own install videos, especially for the A3 version since there are very few on youtube, and are for the A1.

Ordered on wed, received Friday. Ran a few rounds on Saturday. You won’t be disappointed. Watch an install video. Great company, great products, great prices.

Just finished install on this. One note, I didn’t watch a video and assumed this went on the trigger. It goes on the hammer. Definitely dropped the trigger weight noticably, very quick and easy install. I did this, the buffer, bolt release, and charging handle. All items only took about 30 minutes to install. Worth every cent!

A tricky install but trigger pull dropped off about a pound and a half. Not bad for $9. Highly recommend watching the YouTube video twice before and once while doing the swap. Selector detents are tricky, especially if one goes flying across the room. Another great part from HBI for the Stribog.
