    Adding a red or green dot sight to a J Frame revolver

    For anyone interested, it is now possible to add a red or green dot sight to a J Frame revolver. The $50 adaptor to do so comes from AllchinGunParts.com, and hosts a Holosun 507C sight. Adding it to a S&W 517-3 took removing the rear sight and drilling two holes in the top frame. Professional installation was recommended, so mine was done (well) by Armstrong Arms in Laguna Hills. Here's the result:

    Here's the link to the needed adapter:
    Upgrade your S&W J Frame with Allchin's ultra-low profile mount for RMR, SRO, and Holosun C optics. USA-made, competition-proven, trusted by top shooters.

    Does it still fit in most pockets?
