Guns, Firearms, Projectile Weapon Sports/Smith and Wesson model 4546


How do I take apart a smith and wesson model 4546

The 4546 was a 3rd Generation metal frame auto pistol, chambered for .45 ACP. I have owned another 3rd Gen Smith pistol and I found it very reliable and rugged and reasonably was a service pistol, not a target pistol. IMO, the old 3rd Gen Smiths were excellent pistols.

I am giving you a link to Smith's downloadable manual for these pistols that will show you how to take your pistol down for cleaning. I would recommend you print this manual and keep it with your pistol and I also recommend you look for a few extra mags before they go even higher in price.

Link for the manual:

I would NOT recommend you go any further taking this pistol apart than instructed in the manual. I have seen too many guns ruined by people trying to "improve" them after they read some article online...Do NOT change spring rates, add stronger springs or make other changes to your pistol. They are NOT necessary, and you might damage the gun. What parts are available might be found from Numrich - - who might have mags, too.

I really like those big Smith pistols and I think they were among the best autos Smith made.

Take good care of it.

General questions relating to various handguns - shooting, recommendations and general information on older/antique Smith & Wesson, Colt and other US made and European made pistols and revolvers. I am NOT an expert collector, but I have had several hundred handguns over the last 45 years+. I have repaired and refurbished several and shot hundreds of various handguns, and I am pretty knowledgeable on them.


Started shooting in Cub Scouts at age 10. US Army veteran in the late 1960's. Owned several hundred handguns including revolvers and autoloading pistols made by Colt, Smith & Wesson, Ruger, Merwin Hulbert, H&R, Iver Johnson, Hopkins and Allen, Charter Arms and European pistols made by Mauser, Beretta, Star, Llama, Tanfoglio Guseppe, Dreyse 1907 and FN. I am mostly interested in and experienced with late 19th and all 20th century pistols, not current guns using plastic.
