We have a 38 special laser designed for revolvers. It also fits the .357. You would have to roll the cylinder back each time or purchase multiple lasers.
We do offer a discount code for people who want 5 or more .38 lasers.
If you purchase the sled and laser kit with a 38 caliber laser, then add an additional 4 .38 cal lasers to the order, you can use this code in the coupon code box at checkout to save $60: "5pack"
