HOGRIDER Posted August 26, 2023 Share Posted August 26, 2023 Has anyone purchased an MPA stainless or aluminum grip and added it to their existing DS/2011 pistol? Are there aftermarket triggers and/or grip safeties that will work with minimal fitting? https://masterpiecearms.com/cat/ds9-accessories/ds-grips/ No replies from MPA ....... Thanks!

scooterj Posted August 26, 2023 Share Posted August 26, 2023 I have installed X-Line triggers in 3 different MPA pistols. It shouldn’t be difficult to do so with most “2011” triggers. Grip safeties may need some fitting. The MPA grip is cut pretty high. Link to comment Share on other sites More sharing options...

I have a NIB original Geppert/Atlas X-Line Vario Triggers – Medium Flat identical to this one. Purchased it about 4 years ago from Atlas..... https://www.speedshooter.com/product/atlas-x-line-vario-triggers-medium-flat/ Atlas current "X-Line" trigger system appears to have the same features; just not sure if they are still the Geppert version or an OEM Atlas offering: https://atlasgunworks.com/product-details?id=1928697 Thanks for your insight.........

scooterj Posted August 27, 2023 Share Posted August 27, 2023 One of the X-line triggers was an older one that was previously fit to a Cheely grip, was nearly a drop-in with the MPA. The newer triggers seem to have a little thicker material for the bow, but that wasn’t much of an issue. Link to comment Share on other sites More sharing options...

scooterj Posted August 27, 2023 Share Posted August 27, 2023 I think it’s on there. Can’t be 100% sure. I intend to do a complete cleaning after tomorrow’s match and can verify. Link to comment Share on other sites More sharing options...

HOGRIDER Posted September 3, 2023 Author Share Posted September 3, 2023 While I hope @scooterjwill come through with the info on his Atlas triggers having any "logo" on the trigger bow, I thought I would share some info regarding the new trigger offering I received from Glenn at Lone Star Industries. It is similar to an Atlas/Geppert in that the shoe threads onto a post attached to the bow. This feature also allows some "fine tuning" of adding/removing some OAL by the end user for personal needs. It utilizes a #4-40 threaded post and uses a .050 Allen wrench for setting overtravel screw length. I have not fitted this shoe to anything yet, but comparing to an MPA SS grip it would probably need ~.005" to .006" overall removed from the top and bottom of the shoe. Width is fine; and the trigger bow fits the grip perfectly! HTHs Link to comment Share on other sites More sharing options...

HOGRIDER Posted March 21 Author Share Posted March 21 Being inspired by @scooterj's success at installing an Atlas trigger in an MPA grip, I decided that since I really liked the look and function of the Red Dirt USA triggers, I was going to see how much work would be involved in adapting one for an MPA SS grip. I decided the "Cheely" version offered the closest dimensions to the MPA; and that it might be able to work with some dedicated modifications; especially the OAL of the trigger bow which is quiet a bit longer on the Cheely . My first observation is that MPA is dedicating the manufacturing of their grips to be a bit "proprietary" in order to encourage (?) shooters to use the OEM offerings for their replacement triggers. For my personal use, I like a trigger that has a fully supported bow rather than having the front of the bow aligned in the MPA grip's trigger bow channel by the height of the trigger shoe in it's dedicated track. I'm sure others feel my concerns are unwarranted........ After having a Master Machinist friend reduce the thickness of the front of the trigger bow, I was able to utilize the Red Dirt USA trigger, have all safety functions pass, and still have sufficient "pre-travel" to allow full function of the hammer's half cock with full disconnector reset! IMHO, I think it turned out very nice and am in the process of field testing in the very near future. Dry fire, feel, fit, and function are excellent in bench testing!
