I'v been to a few stores and notice some fusions come with a screw in on/off asa and some come with a lever on/off. I one a newer model or are the just different setups. I don't know if one on/off is better or if its just personal preference.
man, i bought an ASA at my local shop and it was messed up. Anyhow, we went back in the shop ( i was playing at the time) and they changed the ASA and we got 10 dollars back. And iit was the same price. But I'm pretty much selling my old ASA and other parts. PM me if you want pictures or questions. =]
If you get the fusion and get another ASA, check it first before you buy.
And i get around 5-10 pods w/ my 45/45. So its around 1400 shots for me. Denpends.
