This is a winner - Chiappa Firearms X-Caliber 12ga/357/38 Gauge Adapter Insert

I paid way more than double for my .22 lr insert from the most popular name brand. I shot both at the same target at 50 yards with just a front shotgun bead. Fired 15 rounds from each. I didn’t anticipate reviewing this product so I didn’t measure the groups but they where identical approx 2.5” groups in the same spot ( 7 o’clock 6” out ). I was extremely impressed and I am almost never impressed. Had I used proper sights the group from this product would undoubtedly have rifle like accuracy. I paid 45 bucks for this product and 120 for the most advertised brand. The fact they had the same zero tells me the same quality went into both products.
