The Ruger® MK series is a favorite for rimfire pistols for competitive shooting sports. The TANDEMKROSS “Maximus” Plus1 Follower for the Ruger® MK series is a drop-in upgrade that makes your gun competition ready - whether you're shooting a Ruger® MKIV™, MKIII™, MKII™ or 22/45™. The “Maximus” Plus1 Follower allows the user to load 11 rounds into a standard 10-round magazine - ideal for rimfire competitions, which allow the shooter to start with 11 rounds. The follower is made of durable Zytel® and is bright red, improving safety by showing the shooter when the magazine is empty.
This is a simple, drop-in upgrade and does not require any special tools to install. The "Maximus" Plus1 Follower is sold in two-packs and works with both the factory magazine base pad and TANDEMKROSS "MarkPRO" Magazine Bumper for Ruger® MKIV™ and "MarkPRO" Magazine Bumper for Ruger® MKIV™ 22/45™. The followers will also work with our extended magazine bumpers for Ruger® MKIII™ and MKIII™ 22/45™

*Please note: The "Maximus" Plus1 Follower is compatible with any Ruger® MK factory magazine base pad and all TANDEMKROSS extended magazine base pads. However, using the Plus1 Follower with a TANDEMKROSS Plus1 magazine base pad does not enable the user to load 12 rounds in a standard 10-round magazine, only 11 rounds.

Quality injection molded plastic, red color let's you see the follower easily after last round. Didnt get 11 rounds in with all ammo, I could only get 10 Browning rounds in. My guess is the ridge on the casings

Great upgrade to my MkIII 22/45. fit is great and it is great to add one more round.

Mr.
The 11th round is a tight fit on my Mk 4 22/45, but it does feed and function very well just like the factory part. Installation is a cinch, took maybe 1 minute for each magazine.

Pusher is ok if you are interested in an extra round in the mag. Does not improve feeding problems in a magazine that is a bad design. Pusher still feeds slowly because of the torque applied by the pusher spring. Pusher spring has way to much force just to try to compensate for Rugers bad design

Sadly this is the only product i have not been satisfied with from TK. I have several parts and love all of them except this part. These plus 1 followers do fitt 11 rounds, but had several malfunctions, also it allows your spring to compress too far which sent my spring flying out the end of the mag upon the first use. I went back to my stock 10 round followers, not worth the hassle. Im not sure if i can return them but if i can i will. they are doing nothing at the moment. disappointing.

Plus 1 follower rocks...
Received quickly, took a few minutes to install, added one extra round, and last round hold open still works fine.

Everything from Tandemkross is outstanding. Never purchased anything from them that wasn’t excellent. These guys really know what they are doing.

I have 4 of these. My Mark iv functioned great, until I added these to my mags. I have a couple malfunctions every time I shoot out of these mags. I have five other factory mags that never jam or cycle incorrectly. I ended up taking them out. I love Tandemkross and have multiple products on my pistol. I really wanted the plus one, but would rather the gun cycle correctly.

Not Satisfied
Even without spring installed, the follower would bottom out on multiple different Mark II and III magazine plungers resulting in last (11th) round having to be wedged and forced into magazine. Refused to spring my magazine lips open. To expensive to have to modify a drop in part. Returned for refund. Thanks
