Update on AZR Model Engineered for SIG MPX
Jun 17th 2026
( UPDATES AT BOTTOM )
Original post:
Going great the SIG MPX is an ammo eating fun gun to shoot thats for sure
When we started the 5000 round durability cycle the man that owns the MPX installed a new set of aftermarket recoil springs as the round count was unknown on the recoil springs he had in the gun since it is one of his favorite guns that gets shot frequently to say the least.
He figures there was 10k rounds on the factory springs when he swapped those out for the new aftermarket ones prior to the start of live fire. SIG Factory calls for 3 years or 5000 rounds so he definetly needed to service his springs before we started.
The aftermarket springs gave up the ghost at the 2450 round mark. Clapped out. Damn need springs.
SIG to the rescue very cool. Called SIG and they launched a set of springs out to us pronto. Left there on the 10th. Great folks over there taking care of everyone thats for sure.
Well somehow theres a "weather delay" in June and the new factory SIG springs are on a weather delay by the carrier. Thats handy. Soon as they arrive we will get back to chewing thru the rest of the 5000 rounds with this bad ass SIG MPX

( UPDATED FRI 06-19-2026 Springs arrived yesterday afternoon. SIG MPX is headed back out to the desert this weekend to work on eating up more of the 5k rounds of 9mm. )
( UPDATED SAT 06-27-26 New SIG factory springs dropped right in and back to chewing thru the 5k rounds last weekend. Till the aftermarket trip bar gave up the ghost and failed inside the gun. New trip bar inbound we shall see if its any better. Once it lands we will get back to it folks. I may have to make yall a trip bar but we shall see. The SIG MPX is performing top notch just as I thought it would. The aftermarket parts for it, not so much. )
( UPDATED MON 06-29-26 New trip bar arrived. First one was thicker than this one. Damn. Now I have to manufacture you guys a trip bar to go with the new MPX model. I like this gun so give me a bit to work out a trip bar that will keep on going and going and going like the SIG MPX does eating 9mm ammo. Standby. )
( UPDATED SUN 07-05-2026 Got to thinking while working on the new trip for the SIG MPX that I may as well go ahead and do 22lr for yall at the same time. Since I have to setup and fixture and program the machines anyway to make one new trip why not go ahead and set another production machine or two in place to run a line trips for everyone. Maybe I should hit up SIG and see if they will make yall a factory one since thier factory parts have done an outstanding job out here in the desert. )
