The trigger on my M-85UL is IMHO very smooth but I have heard that with time it just gets better. Well due to time and mostly money I have only shot 30 rounds or so. I`ve heard/read that if you just sit, say, in front of the TV and dry fire it will help the trigger get even better. Do I need snap caps or will just 5 EMPYT casing do the trick? Thanks for any advice.
