These are really good target guns. But some suffer a trigger guard breakage problem. It turns out that using excessively powerful ammo forces the gun to absorb the excess energy.

Blowback operated guns are a balancing act. If all is balanced (energy from firing verses slide inertia, recoil spring force, slide friction, energy to cock the hammer) then the slide travels and gently kisses the stop in the gun. For this gun that stop is part of the trigger guard. If the energy is excessive then the slide pounds on the stop in the frame. In some cases for this gun it causes the trigger guard to break. If the gun operates reliably on Standard Velocity ammo then NEVER use High or Hyper Velocity ammo in it.

The breakage problem is also because of a manufacturing flaw in the trigger guard. The guard pivots counter-clockwise around a pin in the frame for disassembly. It has a short vertical arm and a long horizontal arm. The design was suppose to be that the trigger guard rotates clockwise on re-assembly until the vertical arm hard touches the gunís frame directly behind the short trigger guard arm. But in some of these guns the trigger guard stops short leaving the vertical arm unsupported. Then the recoiling slide pounds on it in recoil until the vertical short leg breaks off. At one point in time Trailside trigger guard replacements were un-obtainable from this problem. Supposedly Hammerli fixed this problem in the Xesses but I just reviewed a You Tube video from 6 years ago where a Xesses suffered this breakage problem.

It turns out that the top of the long arm of the trigger guard on these errant guns hits the bottom of the frame before the trigger guard rotates enough to get the short arm of the trigger guard positioned hard against the frame behind it. The fix is to remove material from the top of the trigger guard long arm so that the trigger guard can rotate far enough to allow the short arm to firmly seat against the frame behind it. Once supported the short arm is not subjected to the un-supported pounding of the slide in recoil, but it just transfers the recoil hit to the frame directly.

The Trailside and Xesse are ECON version of the famous Hammerli 208. The trigger guard on the Hammerli was a machined part and not a casting like on the Trailside and Xesse. The top of the Trailside and Xesse trigger guard is a non-machined surface with a peaking required draft angle to allow removal during casting. The casting peak is keeping the trigger guard from fully rotating.

The fix is to file the top of the long arm of the trigger guard's top surface until the short arm seats hard against the frame behind it. It may take a few file passes or many. Every gun is a bit different. Once completed the fix is hidden from view but a bit of paint or magic marker will hide the flattening of the top of the long arm of the trigger guard.

If nothing else inspect the trigger guard to be sure the trigger guard rotates far enough to firmly support the short arm against the frame behind it.

I found the gun a bit light and added a red dot to allow more accurate sighting and to add a bit of weight to steady it during firing. Unfortunately mine is the short barreled target version which was all that was available at the time of initial release years ago. But it does fine none the less.

Good luck with your new-to-you gun. Hope this helps. Contact me directly if you need further help.
