There have been some design changes in the Mk V. The counterforce screw now comes with an aluminum block on the end. The bottom support screw now has an aluminum block mounted on it that rotates. Much easier to deal with than the original design. The plastic tips on the swivel set screws have had durability issues. They have been replaced with steel caps that are covered with a non marring pad. Replacement pads are available at Home Depot, Lowes, Walmart, Amazon, etc. and are very inexpensive. You can use either the rubber tripe that are supplied, or the felt ones.
The powder coated that I was using very tragically died. I have not yet found another shop to do this. I keep looking, but my work is not of a sufficient volume to interest anyone so far.
Merry Christmas and I wish you a Happy, Healthy and Prosperous New Year.

JMT MK III
JMT MK III
The NEW JMT Mk lll Mod l "Xtream Duty" sight pusher is a heavy duty tool for moving very tight sights. The Mk lll is now being produced with a powder coated frame for added durability as well as looking a whole lot nicer.
Though originally designed for 1911 and S&W autos, it works on most pistols with flat slides and dovetail sights, including: Glock, HK, XD, M&P, including the Shield, Ruger, and Taurus. Those with slide mounted safeties must have the levers removed.

JMT MK IV
JMT MK IV
The JMT Mk lV is a similar tool for slides with safety levers, that works with all models that are covered by the JMT Mk lll. For odd-shaped slides, such as the XDm, the JMT Mk V is currently being tested and patented. Though not yet pictured, the Mk lV is now being powder coated also. There is a slight price increase to cover this cost.

JMT MK V
JMT MK V
The JMT Mk V is a completely new design which allows its use on pistols with odd shaped frames such as the XDm. It incorporates a unique suspension system to hold the slide, and can be used with existing JMT accessories, such as the M&P pin set. Needless to say, it also works with traditional slides as well. The frames are made from heavy wall steel tubing that has been powder coated. The swiveling screws that contact the slide are made from Delrin to help protect the finish.

For S&W M&P pistols, use our optional set of push pins ($15) for the stair-step rear sight. They also are nice to have with Novak rears, but not essential. Effective immediately the "pin set" has been redesigned and replaced with a set of round to square adapters which perform the same function. There is a set of two adapters, 5/16" and 1/4". These adapters are more versatile and will fit both front and rear sights on most "Novak style" sights. The 1/4" adapter will fit Kimber front and rear sights. A 3/16 adapter will be necessary for S&W front sights. The 3/16" adapter will require a different jackscrew and pin size. This will be provided as a set at a cost of $18. The 1/4" and 5/16" adapters will fit any of the current jackscrews that utilize a 3/16" pin and can be used with the Mk lll, Mk lV , or Mk V tools.
We also offer plugs to replace the internal locks on S&W revolvers. They are available to fit K,L,N frames, or the J frame. These come in stainless or, blued carbon steel. Cost is $34.99 each.
