Mr President
Awesome value. The quality is first class. However the kit could use a complete trigger kit with sear so I don’t have to buy that from Volquartsen. In the 22/45 the TK trigger is a marked improvement over stock but it’s a rough pull without a sear. Also, I would like to see the thumbrest as an option for an “everything” kit. Overall the kit is a must for the 22/45!

I love the kit. Awesome performance. I just shot 500 rounds with 2 misfires, not a single jam or other failure to speak of. I credit that with the upgrades this kit provides. The trigger is fantastic. And the extended release is spot on. And the slide pull saves the skin that was being chewed before putting it on -- just be careful when installing the slide pull so it doesn't interfere with the takedown latch locking closed. (This had me scratching my head for a day, as its not an obvious thing when its happening, as you can't see any evidence that it is the reason.) My only real gripe, though? I had to take it to a gunsmith to do the entire install. (I did some parts.) And I really wanted to be able to do it all by myself, and I tried. But there are too many failure point in the process, no matter how many videos there are of the girls that are supposed to make it look easy. Its not. And in my case, I'm glad I used a smith, as 2 of the springs were undersized, which he just swapped out. I wouldn't have known to do that and might have thought that the upgrades weren't that good in the end, as performance might have suffered and I would not have been the wiser. As such, I'm better for using the gunsmith. So is it a good purchase? YES. But consider the smith's time in the overall total cost. With my red dot, this kit and the smith, I'm at more that the cost of the Mark IV Lite by itself. But now it shoots 500 rounds of crap box ammo without blinking an eye. Oh, and the included magazine loader "gift" is a finger saver that I would have paid $$ for, but this is comes free. Nice touch!

The Everything kit is superb. My gun went from being mediocre to exceptional! The comp balances the gun well. The halo is great for loading cartridges. The trigger is consistent and the adjustable pretravel and stop screws make it a joy to shoot. The mag bumpers are easy to get out in a pinch and look great on the Factory frame. The ejector is well cut and much sharper that the over tumbled factory ejector. I absolutely love it and look forward to upgrading the comp and putting on some Hive Grips. The customer service is professional and courteous with quick responses and tandemkrosses technical assistance and videos make it easy to do the installs yourself. Thank you! I couldn't be more pleased
