The Rogers Shooting School Tap Rack Training Aid (TRT) was developed to safely practice dry fire and reloading drills with the magazine in place. The TRT leaves zero chance of accidentally loading a live round, and removes the need for dummy rounds. Also available in 9mm/40 and .45ACP on Amazon. Due to the differences in tolerances and designs of different .380s this pack includes three purpose-made .380 TRTs (green) and two modified 9mm TRTs (orange). The Sig P365, for instance, requires use of the modified 9mm TRT while handguns like the Glock 43 and M&P Shield Bodyguard use the .380 TRT. Some fitting may also be required, feel free to contact us with questions. We have noticed that certain Ruger .380 handguns fail to work properly with the green .380 TRT. To fix this, approximately 3mm of material must be removed from the front/rear wall of the TRT. This is most easily done with a fine file and should not take more than a minute or two. A picture of the modification can be found on the left side of the page. In some cases, the .380 TRT pack may fit 9mm handguns that dont work well with the 9mm TRT. We are still compiling a list of 9mm handguns that prefer the .380 TRT.
