I can see where that modification would lower the initial force to cock the pistol. How it would affect the guns function I do not know. Over coming the bolt rotation spring is another factor in cocking the pistol. I still bet that the recoil springs are less that what Auto Mag Ltd used on their builds. The springs they used, I assume, is what is required to keep from battering the frame. My older Auto Mags are much easier to cock that the Auto Mag Ltd pistols I have. The older guns also have a lot more rounds through them. What loads are you running in your pistol and are you seeing any battering in the frame? Another question I have is why they did not incorporate this feature in their production pistols if it works? I know in talking to Patrick early on in his ownership of the company that the force required to cock the guns was something he and Tim were working on to improve.

My recent loads have been 240 grain FMJ 20.6 of H-110. It appears the smoother the unit functions not firing the smoother everything works while at the range. the hotter the loads the better. When time permits, I'm also planing on taking down some data on the springs currently installed, material dia. but I'm assuming these are Wolf springs, they are shorter about 1.5" then the older springs that are longer & are smaller dia. , like old stock springs. I don't know when the cut in the Helix was implemented.......but I do know it makes a HUGE improvement ! I can see where that modification would lower the initial force to cock the pistol.

I have one of the last ones made in Loris. Maybe the rotation spring is what's making it so hard to rack the bolt. I complained to Rob @ Auto Mag, and he sent me a link to an official video, on cocking the Auto Mag. He also sent me a free cocking assist tool. It's a T handle made of carbon fiber. https://www.youtube.com/watch?v=KrG7A--GQGg

I have seen that official video Auto Mag LLC video. If your Loris LLC bolt has a left side Helix cam that looks like this you will have problems manually racking back the bolt.  |

I have found it’s childishly simple to rack the bolt in a new gun if I first depress the end of the barrel against the bench. Doing so forces the barrel extension rearward and causes the bolt to rotate and unlock. Then it’s a doddle to just pull back on the cocking piece.
I think it’s the super strong rotation spring that’s causing the difficulties. I would be very hesitant to start machining on an irreplaceable bolt when all you have to do is alter your technique slightly….

Yes there are several ways to rack the bolt as you can see from the other video. But I didn't do any machining on my bolt, some guns that left the factory had a steep Helix Cam cut & some had a very low exit cut & this helps to just rack the bolt like any other gun.
