To replace my old trusty Mark I, which has run into problems stripping bullets from the magazines. Also for the easy take down - so much easier than the first generation.

Great Price for a great gun made in America. Now that they have made a much better take down and assemble procedure it's a keeper.

Good price for an accurate shooter of paper targets.
Paul L on Aug 26, 2018
I already have a mark IV target, last year I put over 10,000 rounds through it. It has a red dot on it, figured this would be a nice add on firearm for iron sight shooting.
Robert G on Aug 23, 2018

How many mags come with this gun?
barbara on Aug 23, 2018
BEST ANSWER: It comes with two 10 rd magazines
Can you add a top picatini rail on this one?
Bob on Oct 6, 2018
BEST ANSWER: There are 3 tapped screws on the receiver that should work fine. I mounted a rail and 3x scope in my Mk 2 for hunting. Will shoot quarter size ragged holes at 25 yards with cheap ammo. Have fun!
Is this California legal?
James on Jul 31, 2018
BEST ANSWER: this gun should be 50 state legal, but with California being the state it is in ,it is almost impossible to what is legal and isn't. i believe there is a web-site in california that will tell you the correct answer. good luck with it, they are fine little pistols.

Ruger Mk IV
I had a Ruger Mk III a number of years ago. It was a very nice extremely accurate and reliable pistol. The only problem is that it was a nightmare to field strip. Fast forward to 2019. I found myself needing a good relatively low cost 22 cal target pistol for the NRA pistol classes I am conducting. I found out that Ruger had come out with the MK IV. It was supposed to be every bit as tight a pistol as the old MK III but MUCH easier to field strip. I shopped around and found the prices at GrabAgun were dramatically lower than anywhere else I could find. I ordered it, it came into my favorite gun store 2 days later, exactly what they told me would happen. The pistol is every bit as good as advertised, and GrabAGun was the very rare combination of a great price and excellent service. I WILL buy from them again.

My first target pistol
Uncomplicated process of ordering and shipping to a valid gun store near me. I searched the internet and GrabAGun had the cheapest price. That was good enough for me. Now that I've gone to the range a bunch of times, I could not be more pleased with the purchase. Simple gun to take apart and clean. Mark 4 is the way to go!

Very Impressed with the service
Had never used grab a gun. I definitely will again, cheapest around and I had the gun at my ffl not 24 hrs later. As far as the gun itself goes I like that a lot. I’m very pleased with the quality and accuracy after about 500 rounds down range. I did have my front sight loosen up which I had been told that they have a tendency to do so. I would put loctite on the screw right out of the box and solve that problem. Very very happy with my experience with grab a gun and I’m about to order a new glock through them as well.

Ruger quality
This little .22 is rock solid and a joy to shoot.
Good weight, well balanced, and decent trigger.
Glad I picked up the 22/45 that has the classic 1911 grip.
GrabAGun even through in a new T-shirt!

Great little gun for a good price
Great price, good build and good accuracy. Hasn’t misfired in the 200+ rounds I’ve put through it so far.
Love the 1911 grip
One bad thing though is the safety. It’s ambidextruous which is good for lefties but it’s position/resistance is such that if you’re not careful, you’ll put the safety back on with your grip and the gun will stop firing (because the safety is now on)

Have shot 200 rounds. Had 2 misfires. Could have been the ammo. Really like the feel of the gun. Cleaning is a breeze.

Ruger's Mark IV features a simple, one-button takedown for quick and easy field-stripping and proper chamber to muzzle cleaning. The recessed button in the back of the frame allows the upper receiver to tilt up and off of the grip frame without the use of tools. Its internal cylindrical bolt construction ensures permanent sight to barrel alignment, while the contoured ejection port and easy-to-grasp bolt ears allow for durable and reliable operation. The accurate sighting system features a drilled and tapped receiver for Weaver- or Picatinny-style rail. The Mark IV is a single action and utilizes an ambidextrous manual safety, push-button magazine release located on the left side, and an ergonomic bolt stop. Included is a washer and two magazines. This 22/45 model features a 5.5" bull barrel, polymer grip frame, blued metal finish, black synthetic grip, and a fixed front sight with an adjustable rear.
