Bought one almost forty years ago, put it on a Model 36, took it right back off. Didn't like the way it felt, & ugly as all get out to boot. Just sold it on eBay, when all was said & done, got $34.00 out of it, not bad for having paid $3 or $4 for it. I really doubt there's enough market for them to sustain a "start-up" business, too many associated costs to make a go of it. I REALLY DO NOT understand the attraction of the things, myself. Even at the MSRP of them, one can buy synthetic Boot Grips for about the same price, & the grips function much better. Many here hate the looks of rubber grips, & that's OK, yet love an add-on, cheap looking grip adapter.I guess Tyler's just aren't my cup o' tea, & I guess I'm glad I don't have to WAY overpay to get one!
