The guys over at 308AR.com like Elftmann Tactical triggers in the 308AR/AR-10 platforms and that’s a pretty substantial endorsement as they can be quite picky. For me I like the idea of a purpose built trigger specifically for pistol caliber carbines.Pistol caliber AR-15’s like AR-9 and AR-45 operate on a blow-back design which can be tough on lower receivers, trigger pins and of course triggers.I don’t hands on yet but I will own one of these triggers soon.

Elftmann Tactical AR-9 Match Trigger

The ELF AR-9 Drop-In Match Trigger has been built for performance. Specifically developed for 9mm and .45 PCC platforms, after tens of thousands of rounds of testing in all platforms, the boss has decided this is the best trigger we have ever produced and does it all in every AR platform. It has a u-shaped captured disconnector that forces a positive hold on the hammer and also has a “pad” that matches up to an extension on the hammer. The pad is directly in line with the rear trigger pin so when the hammer is stopped by those matching surfaces it effectively eliminates trigger slap from the hammer hitting the disconnector and greatly enhances the feel of the  trigger during live fire. Absolutely compatible with the Sig MPX!

All our performance series triggers utilize aerospace grade sealed bearings, making for an incredibly smooth and fast trigger pull. Pull weight is so easy to adjust it can be done in seconds without removing the trigger from your lower receiver. A second-to-none drop-in trigger system that is strong and light, made of wire EDM machined, hardened A2 tool steel and lightweight aircraft grade aluminum. Installation can be done in minutes using your AR’s original hammer and trigger pins. The match trigger may be ordered with a curved or straight shoe.

The amazingly short take-up, glass-rod crisp break and next to zero over travel can be compared to the finest custom 1911 triggers. Adjustability puts you in charge based on your current use. If you are looking for the finest adjustable trigger for your AR-9 / AR-45 platform, this is the trigger system for you.

9mm AR15 Trigger

The 9mm AR15 Trigger is easily where the most confusion lies with the 9mm AR platform. My own research was met with a lot of “Should work” , “Most 2-Stage” and similar vague answers. One of the problems is most AR15 TRIGGER manufacturers have not tested their triggers in 9mm AR15 rifles. The other problem is there are two different kinds of 9mm AR15 BOLT CARRIERS, ramped and un-ramped. We will get into specifics below.

I would like to take the mystery out of the 9mm AR15 TRIGGER. Please use the button below and share the specifics of your build.

Note 1: I use the term “BOLT CARRIER GROUP or BOLT CARRIER” which is not entirely accurate when discussing the 9mm AR15. Technically speaking the 9mm AR15 utilizes a “BOLT“. I use the term “BOLT CARRIER GROUP  or BOLT CARRIER” because that what many shooters are used to referring to in an AR15.

Note 2: This page is a discussion of AR15 HAMMERS and AR15 TRIGGERS in 9mm AR applications. The conversation gets more complex when a .223 5.56 AR15 UPPER RECEIVER and a 9mm AR15 UPPER RECEIVER will share a common LOWER RECEIVER. That’s a topic for a different day and page.


AR15 TRIGGERS with a “Rounded” M16 profile are required for 9mm AR15 RIFLES with RAMPED BOLTS and 22lr AR15 Rifles.

Heres is what we know for a fact about 9mm AR 15 TRIGGERS.
