Hammer Extension

I was concerned the hammer extension would not fit my Marlin. It fit my Marlin 1895 guide gun in 45/70 perfectly. I was so happy. Thank you for your fast service and excellent product. Stephen Greenwood

Only 1 suggestion

I think that it could be a little more solid feeling by not taking out so much material where your tumb sits. I'm sure it is to keep it light,but to me I would prefer more
Material in that section (not bored so wideand thin) Overall fit on hammer was perfect. Was able to install with scope mounted so no need to wait for the extension.

G1 Contender

Just got a TC Contender with a scope. Not much clearance between the hammer and scope, so decided to get a hammer extension. GrovTec seemed to be the best, so I ordered one for my Contender and one for my 1951 Marlin. Installed and used on the Contender, and very pleased and satisfied with the product and my online experience with GrovTec.
