Sawn-off duels mostly require you to switch to desert eagle and/or tec-9/uzi during a reload. With this mod, you can quickly switch to each weapon respectively with a single key. Keys may be customized through the .ini file.
Default keys:
R - Desert eagle
5 - Tec-9/Uzi
(This mod was scripted MAINLY for SA:MP, but also works on single player.)
(In the next release, Imma add a key where you can switch to sawns/combat shotgun. Too lazy ATM.)
