All of my "J" frames have Tyler T's paired-up with factory Magna's... I've tried all kinds of grips for the J-frame from the Rubber-Boot kinds to the oversized Altamont's, etc... I have a shoe-box full of ****** Pachmayer's and other lame aftermarket grips substitutes...

What is sleek/non-bulging, doesn't bunch up the cover garment (shirt) as to show I'm wearing a Revolver, gives a very ergonomic, positive purchase grip upon presentation during both drawing and while firing... for me... is the Magna-Tyler T combo. I suspect it's the same for a lot is why the Tyler-T still is a thing. I buy them from vendor's other than Tyler-T themselves and get them in fast order. I also have a pair of them in "N" frames but find that OEM "Combats" carry well so the N frame Tyler Adapters stay in a bag hanging on my peg-board wall above my gun-bench. I save them for when/if someone here or there needs or would like to try a pair of them in quick order as I have a business account with Fed-Ex and UPS.
