Outstanding in every way. Parts were correct. Shipping was fast. And the company kept me apprised of every detail. I highly recommend Top Gun.

Super fast shipping; easy install. I watched a YouTube video for that. Installing the new trigger return spring is the worst part (yes, I have the special pliers). :)
This went into an HK45 that I had previously "lightened up" to try and get a decent DA pull. This is now my first HK with LEM (light) and I am really liking it! I almost ordered the kit from another well-known HK parts vendor; but then someone on a Sig forum pointed out that the TGS price was $30 less !!! Very satisfied with this purchase.

I've owned several HK pistols, including an HK45 var 7 (LEM) which I sold and later got an HK45 var 1 (decocker/safety). My first LEM pistol had a very light trigger__too light. Instead of changing springs I sold it. The var 7 had a fiddly control lever (worked sometimes, did not work others). I disassembled, polished, cleaned, lubed__no luck. So I decided to go back to the LEM, hence this kit. The good thing about the kit is the inclusion of a heavy trigger return spring. Not only does that make LEM safer, it is much easier to install than the lighter springs (using the special needle nose pliers made for the purpose). I now know that I can (and should) experiment with hammer spring lengths to get the shortest spring that has reliable ignition. There are no instructions with this kit, so you need to seek out a youtube video, because it is not obvious how everything fits. But it is not difficult to do. Expensive, but now my HK45 works fine.

Easy to install with the online video helps. Only shot a hundred rounds since install but like the trigger. 1st shot is a long 4-5 lb pull with a crisp break at the end. Reset is short with a lighter/shorter pull. For me: Advantages - simplification (nicer 1st pull than double action, no safety to mess with. Disadvantages- no safety, 1st shot is always a long pull (with DA/SA set up you could just cock the hammer to have your 1st shot just like all the subsequent shots.)

Trigger is a big improvement over the V1 trigger. No levers to get in the way and every trigger pull is consistent.

Fast shipping. Better pricing and customer service than hkparts.net
