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, including the "Plus1 PRO" Magazine Bumpers.

Don’t waste time in competition with a 10-round magazine. Load more ammo with the TANDEMKROSS “Maximus" Plus1 Follower for Ruger® MK series!

*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.

Nice Upgrade!
Just got a set of these. Very easy to replace the stock followers in my Mark IV magazines, less than 5 minutes. They work just fine, adds additional space to fit an 11th round. Nice little upgrade!

Breaker of things
Excellent replacement for stock follower. Love the red vs stock black. Always helpful to have a plus 1.

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
