Glock17open Posted June 2, 2019 Share Posted June 2, 2019 I just bought a mark IV 22/45. I have put an SJC comp on the gun and installed a c more sight. I built this gun as a practice pistol for my open gun. (It's a CK arm gun). I want to shoot steel challenge and practice with it. I am headed to the range tomorrow, for the guns first trip. Any suggestions for r other mods, it's bone stock. Except for the addition i mentioned. It won't let me upload a pic. It says the image is too big Link to comment Share on other sites More sharing options...
AzShooter Posted June 2, 2019 Share Posted June 2, 2019 A Volquartsen Accurizing Kit will do wonders to the trigger. My Mark IV 22/45 came with a terrible 6 pound trigger. It felt like I had to pull through the safety during each shot. With the Accurizing Kit my trigger is now just under 2 pounds and is very reliable. The trigger also lets you adjust overtravel and pretravel. Link to comment Share on other sites More sharing options...
SteelCityShooter Posted June 2, 2019 Share Posted June 2, 2019 +1 for the Volquartsen kit. My MkIV Stainless Target came with a 5-pound trigger pull that wasn't as bad as AZShooter describes but bad enough. The VQ kit reduced it to a very clean 2-1/2 pound pull free of creep and drag. Mine has a Vortex Venom mounted on the Ruger Picatinny rail and I've used it for Steel challenge too. Enjoy yours. Link to comment Share on other sites More sharing options...
Matt1911 Posted June 3, 2019 Share Posted June 3, 2019 Getting rid of the magazine disconnect and smoothing out the plunger on top of the trigger will do wonders for the pull weight without having to drop a bunch of cash. Link to comment Share on other sites More sharing options...
outerlimits Posted June 3, 2019 Share Posted June 3, 2019 all of the above. also, do the magazine hack on tandemkross' site before you have to. Link to comment Share on other sites More sharing options...
Glock17open Posted June 4, 2019 Author Share Posted June 4, 2019 (edited) Thanks for the input, first trip to the range was a success. Love the comp, I shot some CCI stingers and there was no dot movement. After getting it sighted in I consistently hit an eighth inch steel plate at 50 yards.

AzShooter Posted June 4, 2019 Share Posted June 4, 2019 Pictures please. Congratulations on getting it right. Stingers are a little hot. You may want to try Mini Mags and then CCI-SV for competition. Link to comment Share on other sites More sharing options...
Glock17open Posted June 4, 2019 Author Share Posted June 4, 2019 I will work on the pic, later. The stingers were a test. I also shoot Winchester, federal and Remington. All function Ed flawlessly. Link to comment Share on other sites More sharing options...

dapribek Posted June 6, 2019 Share Posted June 6, 2019 “ After getting it sighted in I consistently hit an eighth inch steel plate at 50 yards.” Hi, do you mean eighth inch square or an eighth inch thick? Just curious. Thanks. Link to comment Share on other sites More sharing options...

verla Posted September 1, 2019 Share Posted September 1, 2019 One of the better set ups I have found is the ruger MK III/IV with a C-More 6/8MOA sight, volquartsen trigger group and volthane grip. It is hard to beat this setup for the price and it will go head to head with any of the more expensive pistols for use in steel challenge matches. Any of the 40gr copper plated bullets do well in this set up- I like CCI mini mag or Winchester Super-X. Both of these seem to function very well.

Polaris13 Posted September 23, 2019 Share Posted September 23, 2019 +1 on the Volquartsen kit, Tandemkross trigger and other goodies and patience for break in. Also +1 on the Tandemkross maqazine tweeking, my gun was a bit finicky before this. Mine eats CCI Blazers and shoots like a lazer once broken in (over 1000 rounds to break in).

MCGILLA Posted May 30, 2020 Share Posted May 30, 2020 What model CMore sight are you running looking for one, and wasn’t sure on dot size? Thanks Link to comment Share on other sites More sharing options...
gerritm Posted June 1, 2020 Share Posted June 1, 2020 We run 6MOA railway on an Allchin mount. Take off the Picatinny mount and this will go direct on the top. Also run a 6MOA RTS2 on an Allchin mount. I have a TK trigger & comp and replaced the bolt with a Volquartsen and removed the loaded chamber indicator. We use CCI mini mag ammo with Volquartsen high power springs in the mags. Guns run 99.9%. Love them. gerritm Link to comment Share on other sites More sharing options...

AzShooter Posted July 4, 2020 Share Posted July 4, 2020 There are no ends to the amount of customizing you can do to your Mark IV. I opted to produce a Mamba on mine and with the then extra upper I bought a lower from Wirthwein guns and ended up with another Standard Mark IV 22/45. I put C-More sights on both. I also have a 5.5 inch bull barrel and a 10 inch barrel that I can swap out. The 5.5 inch will be used for RFPI. Link to comment Share on other sites More sharing options...
