First time ordering from Buds and the whole transaction went really smooth, granted the shipping and transfer with the FFL took a little longer, but it's expected since we are all going through COVID-19 right now and is most understandably expected. The gun was excellent condition, no marks or scratches at all. Can't wait to shoot it at the range once everything opens again. I will definitely order from Bud's again. Getting all my revolvers this year (S&W 629, 460XVR, 610) from Bud's. Thanks again!

Double action takes some breaking in. Very light and for the size extremely powerful.

This was my first purchase from Buds. I was very pleased with every aspect of the purchase. I was looking for a reasonably priced Smith air weight.
It was easy to find on the site. The purchase, shipping and transfer went without a hitch.

My 637 is a keeper. Rated for +P it handles my light reloads, standard factory, and Remington +P hollow points. Fixed factory sights are dead on at the range for which the gun is intended.

Thumbs up Buds👍!

I have always wanted a snub nose 38 and so I decided to order this baby from Buds. It’s a very nice gun, I didn’t spend the extra money on the trigger job but it’s a nice pull any way. I like it!

S&W 637 Airweight very light, but can still handle the stronger 38Spl +P rounds, got it for it smaller size and light weight and what feels like light trigger pull, the Wife has trouble holding the heavier 38’s, 357 or Simi autos 9’s but this one fits her small hands and with light recoil 90 grain whole points it covers the needs for a short range defense firearm.

Great little revolver that goes bang every time.

I conceal and carry everyday. My primary conceal and carry is an officers model 45acp, however there are times the 45 is a little difficult to conceal. I choose the Smith & Wesson Airweight Model 637 for it’s light weight design that has been proven by over 50 years of service. It is easy to conceal in a angle or pocket holster and with its 38 +P load rating it has the knockdown and penetration power I know I can trust. I could not be happier with this little jewel. Quiet surprised how easy and accurate this pistol is out to 15 yards.

Great little gun, and surprisingly accurate to be a conceal firearm. It is lite and despite being lite it is very controllable. Although that\'s partly in it being .38 vs .357. So if you\'re looking or a reliable wheel gun to keep on you, this is a very good option. Gave 4 stars due to the surface is oxidizing on the frame where my Bianchi IWB holster dosen\'t keep it off of my skin. So sweat will affect the finish of this firearm over time. Even though I clean it once a month, it still has that minimal oxidation where the S&W logo is etched in the frame. But I bought it to use and guns are tools.

I placed my order through Buds on a Monday and the gun was ready for pick up at my local FFL Dealer by Thursday. Great communication and fast service from Buds. The revolver itself is awesome, it arrived in perfect condition. It has a very smooth finish and feels great in the hands. I bought it for my wife to carry and she loves it. Even though it is a small framed revolver the recoil of the .38 special is very manageable. 200 rounds have gone through it without any issues whatsoever. Very fun, reliable, and straightforward. If you\'re considering one of these you can\'t go wrong with it. Thanks Buds!
