My advice is: either be a buff-based martial character or a spellslinger dip-based blasting character. Don't try to be both. A spellslinger 1/Sorc 19 never actually 'fires' the gun except when absolutely necessary: he mostly just channels spells through it. A Spellslinger 1/Gunslinger 1/Eldritch knight 10/Evangelist 8 shoots things with the gun and mostly uses spell slots to buff the gun and him/herself.
