Narrative:

While on final to runway 16L we received a traffic alert quickly followed by a traffic RA. I was hand flying; on localizer and on glideslope just outside of the leets FAF. We descended below glide path due to the RA and once clear of conflict we returned back on glide path. I was able to see the aircraft X which caused the RA. The aircraft was on visual to runway 16R and came within about 300 ft. Of ours. From what I could see aircraft X may have overshot the final to runway 16R which likely caused the RA. We told tower and continued on to a normal landing.
