based on what you have and don't yet want to invest in a significant trigger upgrade, good ammo. That said, i like the JP spring kit. it's very affordable and will lighten the pull significantly. does nothing to clear up any gritty feeling. FYI, the warning that comes with lighter springs is that it may not strike the firing pin hard enough to set off harder military type primers. I;ve not experienced this problem but i generally don't shoot surplus ammo but apparently the mililtary has. which is the official stated reason why, along with safety for accidential discharge, the milspec trigger is the way it.
