  1. Savage Model 24 O/U 22 LR/ 20GA

    Posted by Paul on 6th Feb 2014

    The adaptors look well made. Although, not used yet, it adds a lot of flexibility to shoot 410 from the lower barrel! It fits perfect!

  2. Works Great in my 1926 Ithica side by side 20 Gauge

    I originally ordered a 12 gaue to .410/45 Colt Long for my 12 gauge pardner crack barrel shotgun. Since I liked the 12 gauge version so much I went ahead and bought 2 of the new 20 gauge .410xcolt 45 long. Never been happier with a product Keep up the good work

  3. Adapter 20 Ga to 410 Ga - Great Product

    Posted by Andy on 1st Aug 2013

    I have a 20 Ga single shot shotgun and I bought both a 20ga/410Ga adapter and a 410ga/22lr adapter. With both of the adapters installed (one inside the other) it shot the 22lr well. So now I have a choice of the three calibers.
    This is a Quality produce. I would recommend this to a friend!!

  4. Top Quality 20ga. to .410/45LC Adapter

    Posted by Bill in Colorado on 1st Jul 2013

    I finally had a chance to try it yesterday and was using it in a modified H&R single shot 20ga. I ran 2 1/2 and 3 inch slugs, #4, #6, #9 and some 45LC through it, and all functioned perfectly. Interesting was that the 45LC had much less recoil than the 1/4 oz slug I tried....guessing it is the fast burn rate of the shotgun powder compared to the 45LC ? Anyway I did have to use the rod to clear all of the shotshells out of the adapter, but the 45LC rounds just dropped out.

  5. Awesome

    Have the 410/45LC, and the .38 Special. Helps to have one gun that can shoot four types of ammo! These products are made sturdy and for a very reasonable price! Deciding which one to get next!

  7. one shotgun standing in the corner = 10

    Posted by Charlie Reynolds on 2nd Dec 2012

    I bought my first adapters for my son-in-law but I think these adapters make all the sense in the world and will be ordering more in the near future for myself. Thanks Charlie

  8. Fantastic Product

    Posted by Jr on 29th Nov 2012

    I purcahsed the 20 gauage to 410 conversion so my daughters can learn to use a shotgun a little more easily. The 20GA really "got" thier attention to begin with! So much that it scared them. Now they love to shoot this single shot, break open firearm once again! Which is amazing and fun for the whole family! Saved me from having to purchase a 410 just to train with! Thanks guys.

  10. 20 Gage to 410/45 Long Colt Adapter

    Posted by George Bowen on 31st Oct 2012

    This is a great product. I first found out about these adapters through Dave Canterbury site at Wilderness Outfitters. The folks as Gunadapters.com really know what they are doing.

    These adapters make the lowly shotgun a gun for all seasons. Now, when you walk in the woods or go hunting you are ready for just about anything that comes along. These adapters are well worth the money and peace of mind knowing you are covered for any situation. Get them while you still can…
