The S.L. Variant earned its reputation as the most secure and positive-loading speed loader in both competitive and real-world venues. The S.L. Variant is a positively loading speed loader; the rounds are forced out with a punch thanks to individually spring-loaded chambers. The S.L. Variant holds its rounds securely with individual locking cams. No more reaching in a pocket to find loose rounds accompanied by an empty speed loader. The large Sport Grip attachment (not shown, sold separately) simply screws onto the Variant's threaded end, giving shooters a better purchase and more secure loading. The Sport Grip is also useful to shooters with injured or gloved hands. The five-shot version will fit any J-frame compatible revolver, the various six-shot models will fit any K, L, or N frame compatible revolver as well as a six shot for .45 ACP.
